Only once did David Foster Wallace give a public talk on his views on life, during a commencement address given in 2005 at Kenyon College. The speech is reprinted for the first time in book form in THIS IS WATER. How does one keep from going through their comfortable, prosperous adult life unconsciously? How do we get ourselves out of the foreground of our thoughts and achieve compassion? The speech captures Wallace's electric intellect as well as his grace in attention to others. After his death, it became a treasured piece of writing, commented on endlessly in blogs, and emailed from friend to friend. A YouTube video went viral, but was recently removed by his trust for copyright infringement.
You can read the book with his entire speech.
As for the video, I count myself blessed that I watched it before it was gone. You may still find a few copies, perhaps this one.
“The really important kind of freedom involves attention, and awareness, and discipline, and effort, and being able truly to care about other people and to sacrifice for them, over and over, in myriad petty little unsexy ways, every day.”
